Output:

The program should provide the user with the following menu options:

- Listing of records in alphabetical order of first name or last name

- Listing of records in reverse alphabetical order of first name or last name

- Search for a record by Last Name and print out the result.

- Search for a record by birthday in a given year or month.

Please also include:

- Insert Record (of course, at the correct location in the sorted list)

- Delete Record from the list by providing the mobile phone number or last name

- Write out the sorted records to the same file before exiting the script.

If not using the sample datafile, then create a text file containing minimum 10 records in the specified format. Your script should reject any record(s) having illegal values, e.g. phone numbers in incorrect format or incorrect zip codes etc., either upon reading the file first or upon a new entry. If you cannot implement format checking for fields due to time constraints, please go ahead and submit what you have.

Feel free to add any other field(s) that you might think is/are important for you to have in a phone book.

You can also add more menu options (functionality) as desired other than the ones mentioned in the next section.

Write your own functions (if allowed by the shell, to do the various menu options)

Programming considerations

Properly document your script by having ample comments throughout the different parts of your scripts

FAQs

Q: Can we have multiple entries in the phone book?

A: No, you cannot, unless one of the fields is different.

Q: What is an illegal zip?

A: Any integer that is less or more than 5 digits long.

Q: What is an illegal phone number?

A: One that does not have 10 digits or is not in the correct format using the hyphens in the correct places. Hence, currently international numbers are not included in the address book.

Q: Do I have to check for illegal address (like incorrect state)?

A: No, but if you can that would be fabulous.

Q: Do I have to check for birth date being a valid date?

A: No, but again, surely try to implement it and I would highly recommend doing it.
